Abstract

Background. Sexually transmitted hepatitis C virus (HCV) infection is an emerging epidemic among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). HCV may be underrecognized in this population, historically thought to be at low risk.Methods. We determined the prevalence and incidence of HCV among HIV-infected men at Fenway Health between 1997 and 2009. We describe characteristics associated with HCV.Results. Of 1171 HIV-infected men, of whom 96% identify as MSM, 1068 (91%) were screened for HCV and 64 (6%) had a positive HCV antibody (Ab) result at initial screening. Among the 995 men whose initial HCV Ab result was negative, 62% received no further HCV Ab testing. Among the 377 men who had ≥1 additional HCV Ab test, 23 (6%) seroconverted over 1408 person-years, for an annualized incidence of 1.63 per 100 person-years (95% confidence interval,. 97-2.30). Among the 87 HIV-infected MSM diagnosed with prevalent or incident HCV, 33% reported history of injection drug use, 46% noninjection drug use (NIDU), and 70% sexually transmitted infections (STIs). Sixty-four (74%) of HCV-infected MSM developed chronic HCV; 22 (34%) initiated HCV treatment and 13 (59%) of treated persons achieved a sustained virologic response (SVR).Conclusions. Prevalent and incident HCV, primarily acquired through nonparenteral means, was common in this HIV-infected population despite engagement in care. STIs and NIDU were common among HIV/HCV-coinfected MSM. SVR rates were high among those who underwent HCV treatment. All sexually active and/or substance-using HIV-infected MSM should receive routine and repeated HCV screening to allow for early diagnosis and treatment of HCV. © 2013 The Author.
